Problems solved by technology

First of all: artificial "scratches" are difficult to ensure consistency, the experimental error is large, there are many interference factors, and manual scratches may scratch the coating on the surface of the culture vessel, thereby affecting the experimental results
Secondly, the cell wound healing experiment requires continuous observation to evaluate the effects of treatment factors on cell migration. The traditional method is to pre-mark the observation position on the back of the culture plate, but the cell growth cannot be predicted before the experiment. Each observation under the microscope It is impossible to be completely consistent, and the traditional method calculates the migration distance of a certain part, and can only obtain the data of local cell migration

Abstract

The invention provides a cell circular scar healing experimental device for a six-pore plate. The device comprises a flake (1), wherein a criss-cross structure (2) is arranged at the bottom of the flake; a cylindrical structure (3) is arranged at the bottom of a cross end of the criss-cross structure. The device is convenient for observing scar healing in the whole visual field, and avoids the phenomenon that only local area healing situation of a scar can be observed in existing cell scar experiments.

Description

technical field [0001] The invention relates to the field of cell biology and discloses a cell wound healing experimental device for preparing circular wounds. technical background [0002] Cell wound healing assay is currently the most commonly used in vitro experimental method to study cell migration ability. The basic principle is: when the cells grow and fuse to a monolayer state, a "scar" is artificially created on the monolayer cultured cells, and the cells at the edge will gradually enter the blank area to heal the "scratch". By calculating the healing rate of cell scars and evaluating the migration ability of cells, the process of cell migration in vivo is simulated to a certain extent. Factors that alter cell migration and / or growth in vitro can increase or decrease wound healing rates, so this assay is often used to investigate the role of various experimental conditions such as gene regulation and drugs in cell migration. The experiment is simple and cheap. [...
